FIELD: oil and gas production. SUBSTANCE: when carrying out hydrochloric acid treatment of beds and installation of acid baths over the period of well development and performing repair works over the period of drilling and operating wells, intensiveness of corrosion of overland and bed equipment is inhibited by means of applying film coating on the surfaces of equipment accompanied with additionally inhibiting hydrochloric acid. Acid treatment of productive bed includes successively pumping in a film-forming solution containing diesel fuel and hydrochloric acid corrosion inhibitor in conjunction with inhibited hydrochloric acid and additional acid corrosion inhibitor. As the first acid inhibitor, paraffin-deposition inhibitor is utilized based on hydroxyalkylated alkylphenols in aromatic solvent. EFFECT: increased oil production. 1 tbl
